5. Introduction to "Emissivity"

5.1. Emissivity Description
The emissivity of the product can be adjusted from 0.01 to 1.00 with the
default value of 0.95. Many common objects and materials (such as
timber, water, skin and textile fabric) can reflect the heat energy effective-
ly. So it is easy to obtain relatively correct measurement value. The
emissivity is usually set as 0.95 when the coarse objects that are easy to
give outenergy. For semi-matte objects that give out less energy, the
emissivity is usually set as 0.95 when the coarse objects that are easy to
give out energy. For semi-matte objects that give out less energy, the
emissivity is usually about 0.85 and the emissivity of semi-gloss objects
is 0.6. The shiny objects are divided into materials with low radiation
coefficient. The emissivity is usually set as 0.3 at the time of measure-
ment. Correct setting of the value of emissivity is very important for you to
carry out the most correct temperature measurement. The surface
emissivity will produce giant impact on surface temperature measured by
